This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Real-time clock battery depleted (if present), Firmware bug, Main board memory issue, Power interruptions during updates

Safety first: Normal handling precautions only.

Steps to check:

Reset time/date: Use the keypad or app to set the correct time and date on the mower.
Firmware update: Connect via app and install any available firmware updates that address clock issues.
Power cycle: Turn OFF the mower for a few minutes, then ON again and verify the time remains correct.

When to call a technician: Persistent E19 with time resetting indicates an internal RTC or memory fault; main board replacement may be required.
